IMPROVEMENT I N GAS-TORCHES.

Specification forming part of Letters Patent No. 220,058, datedSeptember 10, 1879; application filed February 5, 1879.

To all whom it may concern:

Be it known that LEDWARD 00E, of New Haven, in the county of New Havenand State of Connecticut, have invented a new and Improved Gas-Torch, ofwhich the following is a specification.

My invention relates to gas-torches; and consists in a novelconstruction of some of the parts of the torch, and in new combinations,which are hereinafter more fully set forth and claimed.

Figure 1 is a view of the torch, showing the slot in its upper end. Fig.2 is a view of its upper end turned one-fourth of a revolution from theposition shownin Fig. 1. Fig. 3 is a longitudinal section of the tubeand the trigger, showing the parts within the tube. Fig. 4 is a view ofthe hammer and spring formed in one piece. Fig. 5 is a view of thefeeder and of the flat spring to which it isattached. Fig. 6 is a viewof the tapering tubeto which the trigger and handle are attached. Fig. 7shows the spring-hammer in raised position, the fulminate-ribbon beingseen in dotted lines.

To enable others skilled in the art to which my invention belongs tomake and use my improved torch, I will describe its parts and theiroperation.

A, Fig. 1, is a straight tube, threaded on its ends. B, Fig. 6, is atapering tube, on which the lug C is formed. The slot or is made in thelug, and extends into the tapering tube, as shown in Fig. 3. Its smallerend is screwed onto the tube A, and the handle D is inserted in itslarger end. Into the slot at the trigger E is inserted, and is pivotedto the lug, its inner end passing through a slot in the connecting-rodI), as shown in Fig. 3. The spiral spring 0, also shown in Fig. 3, isplaced on the connecting-rod 1), its upper end coming against the end ofthe tube A and its lower end against the trigger E.

The piece F, Figs. 1 and 2, has the slot at in its end, has therectangular groove 0, in which the fulminate-ribbon moves, has the lugsg and notches f, which limit the motion of the feeder N. It is screwedonto the upper end of the tube A. The hammer o and spring M, Fig. 4, aremade in one piece, which has the ln gs m and a, and is fastened to thepiece F by screws.

feed or feeder N is attached.

The lower end of the connecting-rod I), Fig. 3, has a slot, throughwhich one end of the trigger passes, and the upper end of the rod isformed into a stiff flat spring, 12, on the sides of which are formedthe lugs 00, which move in the notches f, for the purpose beforementioned.

To the upper end of the connecting-rod the The feeder has the elongatedlug 7 formed 011 oneof its sides by cutting away the parts about it, thelug making an acute angle with the piece F. The motion of the feeder isso limited that when it is forced back by the spiral spring the ing 1'on the feeder rests on the lug m.

The fulminate-ribbon to be used in my torch is a long strip of paper ofthe right width to move in the slot 6, and has the drops of fulminate atintervals corresponding to the feed. It is inserted into the torchbetween the hammer and the feeder, and passes under the feeder andspringp down into the tube A.

The parts of the torch being thus constructed and arranged, theiroperation is as follows: A pull on the trigger moves up theconnectingrod and feeder, and the lug on the feeder drops into the spacebetween the lugs m and a, lets the feeder onto the fulminate-ribbon, andthe feeder forces it forward, while the lug on the feeder, passing underthe lug a, lifts the upper end of the spring and hammer, which drop andfire the fulminate as soon as the lug on the feeder passes the lug a.The pull on the trigger being relinquished, the spiral spring draws theparts back, the lug on the feeder passing over the lug a, when theoperation of firing can be repeated.

Having described my improved gas-torch and its operation, what I claimas new, and desire to secure by Letters Patent,.is-

1. The herein-described gas'torch, consisting of the handle D, triggerE, tapering tube B, tube A, spiral spring 0, connectingrod b, feeder N,piece F, spring M, and hammer 0, all the said parts constructed andcombined as shown and set forth.

2. The trigger E, spiral spring 0, connecting-rod b, feeder N, piece F,and means to raise and hold in a raised position the feeder as it forcedback, and to press it onto the fulminateribbon as it is moved forward,in combination to move the fulminateribbon, as set forth.

3. The trigger E, spiral spring 0, connect- 6.
